Using AI to price your cards?

[Mattymc727]

Has anyone been using Generative AI or LLMs to price their cards for sale?

I thought it was a neat experiment to see how accurate the results may be. Here is my attempt using the latest version of ChatGPT. My prompt could have been better, with added detail in regards to the back and other descriptions, but thought it was pretty spot on!

Prompt: Hi! I’m trying to sell my T206 SGC grade 1 Evers Portrait baseball card and want to know what I should price it at. Do you have any suggestions?

Based on recent sales and current listings, a 1909 T206 Johnny Evers Portrait baseball card graded SGC 1 typically sells between $250 and $425. For instance, a recent sale on February 8, 2025, closed at $300, while current eBay listings range from $275 to $425 . 

Given this data, pricing your card around $325–$350 could be a competitive starting point, allowing room for negotiation. If your card has desirable features—such as a well-centered image or a popular back brand like Piedmont 150—you might consider listing it toward the higher end of the range. 

To maximize exposure, consider listing your card on platforms like eBay, Heritage Auctions, or LiveAuctioneers, which cater to vintage card collectors . 

If you need assistance crafting a compelling listing description or selecting the best platform for your sale, feel free to ask!
